[Constitution] A coatings composition having vibration-damping of two-components type and coating type which can be cured at the normal temperature comprising:a combination of not less than two kinds of an epoxy resins which can be provided with a curing compounds having each different glass transition temperature and a curing agent for an epoxy resin, and a filler. [Effect] The coatings composition having vibration-damping of two-components type and coating type which can be cured at normal temperature can be provided. Specially, said coatings composition which a drying oven for baking such as conventional example is not necessary because its composition can be cured at the normal temperature in a short time can be provided. Said coatings composition which can be exerted excellent vibration-deadening performance at even machine-instrument-apparatus-parts of using at high temperature because it's composition can be exerted high vibration-damping performance at broad range of temperature especially at high temperature can be provided.
